Transact SQL :: Recursive Query To Assign Values
Jul 30, 2015
I'm trying to find it difficult to use recursice CTEs or better solution for a special request below. There are two tables 1) @sizes serves as a lookup or reference for right drive and 2) @test is sample data with different sizes. Assume that I want to evenly distribute the drive letters from table1 to table2 by checking the size available.
E.g.: for the first record in @test; id = 1 where the size is 50 and it fits in Y: drive -- left over space in Y: = 50
id=2, size 2.5, space available from left over = 50 - 2.5 = 47.5 which again fits into Y:
id = 3, size 51, cannot in fit in Y: drive as there is enough space in Y: to allocate (51 > 47.5)
so pick the next drive check on availability again
DECLARE @sizes TABLE (id TINYINT, size DECIMAL(5,2), drive VARCHAR(3))
INSERT INTO @Sizes
SELECT 1,100.00,'Y:'
UNION ALL
SELECT 2,80.85,'Z:'
[Code] ....
-- My output should look like
col1 , val ,  path
AÂ Â Â Â Â Â Â Â Â 50 Â Â Â Y:
B Â Â Â Â Â 2.5 Â Â Y:
C Â Â Â Â Â 51 Â Â Z:
D Â Â Â Â Â 2.6 Â Â Y:
E Â Â Â Â Â 52 Â Â Â Z:
FÂ Â Â Â Â Â Â Â Â Â 2.7Â Â Â Y:

I have a Recursive CTE for TFS database which gives me below results:
Parent (User Story) level 0
       -------------.Task(Dev) and ask(QA) --
level  1
  BUG level 2
        ---------------Task (Dev) and Task(QA)
level2Â
So, My ParentID column keeps two ParentId one for User story which keeps the child tasks and child bugs and another for Bug Child tasks
I need to update this results and want to see all of the tasks under User story so the result I want is:
User Story:
 Task(dev and QA)
 Task (Dev and QA ) but its should know that these tasks are the bug tasks.

I need to write recursive query to find child of a parent until the last leaf. Below is my code.Â
;WITH Parent AS(
SELECT [ParentID],Value
FROM[DynamicColsValues_TP1]
WHEREValue IS null
UNION ALL
SELECT t1.[ParentID],T1.Value, FROM DynamicColsValues_TP1 t1 INNER JOIN Parent t2
ON t1.[ParentID]=t2.[ParentID]
)
SELECT * FROM Parent option (maxrecursion 0)
When I execute this code. It is returning me millions of rows. Whereas  i have only 20 rows in a table max 40 rows it should return.

I have a table called USERS, some of its records are marked as  hiddenRcord, I want to load those records in a custom page in my asp.net webpage with paging enabled, each page contains 10 records.Â
I use the statement "SELECT Top 10 tableID,userName FROM USERS WHERE (hiddenRecord=0 AND tableID>@tableID)"
The pagination has 5 links (First,2,3,4,Last), I can of course put the last tableID in link number 2, but I don't know how to do it for the links (3,4,Last).

[Code] ...
Here i need output like below
Workgroup Managed Active
'WE' 255 ,400
'EE' 300 ,450

I need limit on recursion. I have a recursion query. which gives me a parent child record set. I want my application to fetch only top 100 rows. In those 100 rows the parent child set should not get break. Even if it gives 105 rows also fine but it should have entire parent child structure.
If you see my below table. where null is the table which dont have parents but have the child.
ITEMID parentItemid
6 NULL
7 NULL
8 6
9 7
12 NULL
13 12
14 8
16 6
17 16
And it is temp table #test1and my recursive query.
;WITH Cte AS
(
SELECT ItemID,ParentItemID,CAST(ItemID AS VARCHAR(200)) [path] FROM #Test1 WHERE ParentItemID IS NULL
UNION ALL
SELECT t.ItemID,t.ParentItemID, CAST([path]+'.'+CAST(t.ItemID AS VARCHAR(20)) AS VARCHAR(200)) FROM Cte c JOIN #Test1 t ON C.ItemID=t.ParentItemID
)
SELECT * FROM Cte ORDER BY path ASC
Here how can i get top 100 parent child set.Â

I have a table with 3 columns , let say (PatientIDÂ int, AppointmentDate date, PatientName varchar(30))
My source data looks in below way..
PatientID       AppointmentDate     PatientName
 1                01/01/2012         Tom
 2                01/10/2012         Sam
 3                02/15/2012         John
I need output in below way..
PatientID       AppointmentDate     PatientName
 1                01/01/2012         Tom   (actual patient record)
 null             01/10/2012         Tom
 null             02/15/2012         Tom
 null             01/01/2012         Sam
 2                01/10/2012         Sam    (actual patient record)
 null             02/15/2012         Sam
  null             01/01/2012         John
 null             01/10/2012         John
 3                02/15/2012         John    (actual patient record)
I need t-sql to get above output. Basically the appointment dates are repeatedly assigned to each patient but only difference is patientid will be not null for actual patient record.
Â
Create table sample (PatientIDÂ int null, AppointmentDate date null, PatientName varchar(30) null)
Insert sample values (1,'01/01/2012' ,'Tom'),
(2,'01/10/2012','Sam'),
(3,'02/15/2012','John')

create table #StuDetails(City varchar(25),StuStatus varchar(25), currentValue int,Week1 int,week2 int,week3 int,week4 int)
insert into #StuDetails values('A','new',13,10,0,0,12)
insert into #StuDetails values('B','Old',10,10,41,0,12)
insert into #StuDetails values('C','Fail',10,9,0,0,5)
select * from #StuDetails
Output of above is display as:
CityStuStatuscurrentValueWeek1week2week3week4
Anew 13 10 0 0 12
BOld 10 10 41 0 12
CFail 10 9 0 0 5
Now for columns Week1 to week3 if value is 0 then i want to display by searching next week value, if it is also 0 then go for next week and if value found there then display instead of zero. so my output would be as below instead of above.
CityStuStatuscurrentValueWeek1week2week3week4
Anew 13 10 12 12 12
BOld 10 10 41 12 12
CFail 10 9 5 5 5

This is a very basic question on replication.
I'm having a central Server with SQL Server 2005 Standard Edition and Other sites with Sql Express Server 2005.
Other sites will also be adding New records and data will be replicated to Central server and from there it will be distributed to all sites.
Question is that if Other sites are also adding Records how i can assing Identity values in those databases. There are few restricitons on this :-
1. I don't want to use GUID.
2. Numbers should be sequential that is after 1000, 1001, 1002 etc. should come.
i thought of adding Negative Values in the primary key on other sites and then when data is replicated on central server then replace it with sequential key but i'm not clear on how to accomplish this.
any help will be highly appreciable.

I am using the following code to get the next immediate parent of a customer in the hierarchy and it works fine. However, it works only for one customer at a time (i made this a scalar function and I pass the customer id as shown below).
How can I modify this so that i can get each customer and its next immediate parent (all of them in one shot in a single data set)?
WITH my_cte (CustomerID, ParentID, Level)
AS
(
SELECT CustomerID, ParentID, 0 AS Level
FROM [dbo].MyTable
WHERE CustomerID = @CustomerID
UNION ALL
SELECT CustomerID, ParentID, Level + 1
FROM [dbo].MyTable e
INNER JOIN my_cte AS cte ON e.CustomerID = cte.ParentID
)
select CustomerID from my_cte WHERE Level <> 0 AND Level = (SELECT MIN(Level) FROM my_cte WHERE Level <> 0)

I am using RDLC report with Microsoft visual studio 2005. In the first page of rdlc i have two text boxes and one table in body section. In the second and subsequent pages i want to repeat the data from textbox1 and textbox2 along with table data continuation of page1.
Currently the continuation of table data from page1 to page2 is working properly. But the textbox1 and textbox2 data also needs to be repeated in every pages.
I tried the following steps, but fails to work.
1. added two text boxes in header section and another two text boxes in Body section.
2. Assigns the dataset value to textboxes in body section.
(Ex: =first(Fields!Address.Value)
3. Assigns the textboxes value from Body section to the corresponding text boxes in header section.
(Ex : =first(ReportItems!textbox1.Value))
Result:
The header text box value displayed in the first page only and not repeated in the subsequent pages.
Expected:
Whatever assigned to the header section should be repeated in the subsequent pages. But only page number, date... is reflecting in other pages and not the text box values in header section.
Kindly give me the solution.
Thanks in advance.

Sql server keeps tellingme that I cannot execute insert or update from inside a function and itgives me an option that I could write an extended stored procedure, butI don't have a clue of how to do it. To quickly fix the problem theonly solution left in my case is to convert this recursive functioninto one recursive stored procedure. However, I am facing one problem.How to convert the select command in this piece of code below into an"execute" by passing parameters and calling the sp recursively again.### piece of code ############SELECT @subtotal = dbo.Mkt_GetChildren(uid, @subtotal,@DateStart, @DateEnd)FROM categories WHERE ParentID = @uid######### my function ###########CREATE FUNCTION Mkt_GetChildren(@uid int, @subtotal decimal ,@DateStart datetime, @DateEnd datetime)RETURNS decimalASBEGINIF EXISTS (SELECTuidFROMcategories WHEREParentID = @uid)BEGINDECLARE my_cursor CURSOR FORSELECT uid, classid5 FROM categories WHERE parentid = @uiddeclare @getclassid5 varchar(50), @getuid bigint, @calculate decimalOPEN my_cursorFETCH NEXT FROM my_cursor INTO @getuid, @getclassid5WHILE @@FETCH_STATUS = 0BEGINFETCH NEXT FROM my_cursor INTO @getuid, @getclassid5select @calculate = dbo.Mkt_CalculateTotal(@getclassid5, @DateStart,@DateEnd)SET @subtotal = CONVERT (decimal (19,4),(@subtotal + @calculate))ENDCLOSE my_cursorDEALLOCATE my_cursorSELECT @subtotal = dbo.Mkt_GetChildren(uid, @subtotal,@DateStart, @DateEnd)FROM categories WHERE ParentID = @uidENDRETURN @subtotalENDGORod

Hello,
I have the following tables:
Article(articleID,CategoryID,ArticleTitle)
Categories(categoryID,ParentID,CategoryTitle)
I am trying to retrieve the main category ID for a specific article ID.
For example lets say I have this data:
Article:
1, 10 , "some title"
2,10,"some title"
3,11,"some title"
Categories:
1, NULL , "some title"
2, 1, "some title"
10, 2, "some title"
11, 10 , "some title"
In this example I want to know who is the main category of article 3.
The query should return the answer: 1
Thats because:
The article ID 3 is inside category 11.
Parent for category 11 is 10.
Parent for category 10 is 2.
Parent for category 2 is 1
and Parent for category 1 is NULL, which means category 1 has no parents and it is the main category.
Query will return article id, category id, main_category_id, ArticleTitle, CategoryTitle (some union between 2 tables)
Do you have any suggestions for such query?
Thanks all.

Recursive quey to show products with "custom defines fields" related by Classifications, instead of per product Hello, I’m working on a project .. .
I’m desperating due to the
complex (for me and also I think for some others) sql query that I need to
write, to show the products with his “custom defined fields� that are inside a ProductsFieldsByClassification
table that holds this mentioned “custom defined fieds� according to the Classifications
table, on where the Products can be found trought the productsClassifications
table.
CustomFields can be defined
and set for the products, trought his Classifications (instead of define a
custom field for each product (that consume a lot of data), I decide to use it as
I explain)
I will to know the properly
SQL QUERY to show a list of products with the ProductsFieldsByClassifications and ProductsFieldsValuesByClassifications:
As example on
a Requested ID_Classification = 16 (Torents/Games/Dreamcast/PAL), the products must be show with the
ProductsFields and Values that has the DBA for the:
·
requested
ID_Classification
o
PAL (ID_Classification: 16)
·
AND all
the Classifications that belongs above (trought ID_ParentClassification) that are :
o
Torrents (ID_Classification:
1) that will show the products values for the “Size�
o
Games (ID_Class..:4) ß this classification has no CustomFields so none from this one.
o
Dreamcast (ID_Class..:14 )
that will show his ID_Classification(14) product field “Levels� value (but not “AllowSave� as not have value for any product)

Hi,
Does anyone know how to do an sql recursion queries?
I believe it involves a view with a union.
I have a User Table and in that table i have a employee_id and a
boss_id. What i'd like to do is to find all employees under a certain
boss.
For example,
Employee_ID Boss_ID
1
2 1
3
4 3
5 2
So if i'd like to know who are under the employee_id = 1 it will return
employee_id 2 and 5 since employee 2 also is the boss of employee_id =
5.
To do that i'd have to have recursion query.
Thanks,

I am wondering if there is some type of recursive query to return the values I want from the following database.
Here is the setup:
The client builds reptile cages.
Each cage consists of aluminum framing, connectors to connect the aluminum frame, and panels to enclose the cages. In the example below, we are not leaving panels out to simplify things. We are also not concerned with the dimensions of the cage.
The PRODUCT table contains all parts in inventory. A finished cage is also considered a PRODUCT. The PRODUCT table is recursively joined to itself through the ASSEMBLY table.
PRODUCTS that consist of a number of PRODUCTS are called an ASSEMBLY. The ASSEMBLY table tracks what PRODUCTS are required for the ASSEMBLY.
Sample database can be downloaded from http://www.handlerassociates.com/cage_configurator.mdb
Here is a quick schema:
Table: PRODUCT
--------------------------
PRODUCTIDPK
PRODUCTNAMEnVarChar(30)
Table: ASSEMBLY
--------------------------
PRODUCTIDPK(FK to PRODUCT.PRODUCTID)
COMPONENTIDPK(FK to PRODUCT.PRODUCTID)
QTYINT
I can write a query that takes the PRODUCTID, and returns all
PRODUCT
=======
PRODUCTIDPRODUCTNAME
--------------------
1Cage Assembly - Solid Sides
2Cage Assembly - Split Back
3Cage Assembly - Split Sides
4Cage Assembly - Split Top/Bottom
5Cage Assembly - Split Back and Sides
6Cage Assembly - Split Back and Top/Bottom
7Cage Assembly - Split Back and Sides and Top/Bottom
833S - Aluminum Divider
933C - Aluminum Frame
10T3C - Door Frame
11Connector Kit
12Connector Socket
13Connector Screws
ASSEMBLY
=========
PRODUCTIDCOMPONENTQTY
---------------------
198
1104
1111
211
281
311
381
411
481
511
582
611
682
711
783
11128
11138
I need a query that will give me all parts for each PRODUCT.
Example: I want all parts for the PRODUCT "Cage Assembly - Split Back"
The results would be:
PRODUCTIDPRODUCTNAME
--------------------
2Cage Assembly - Split Back
1Cage Assemble - Solid Back
933C - Aluminum Frame
10T3C - Door Frame
11Connector Kit
833S - Aluminum Divider
12Connector Socket
13Connector Screws
Is it possible to write such a query or stored procedure?

I have got a table WORKORDER. wonum and parent are the two columns in the table. A wonum can have children.Those children can have children, so on. if i am giving a wonum,it should display all the children ,their children and so on.
Sample data in the table is as follows
wonum parent
7792 NULL
7793 7792
165305 7793
7794 7792
7795 7792
eg:
7792 is a workorder,which has got children and grand children
7793 is a child of 7792
165305 is a child of 7793
7794 is a child of 7792 and
7795 is a child of 7792
When I give the 7792 in the query,it should fetch all the children and grand children,etc.
output should be :
7793
165305
7794
7795
How can we do that?
